I don't know if it's the barley straw or the aeration system--or likely both--but right now the pond has secchi readings of over 3 meters. This is unheard of on any of the ponds on my farm. I have some Earthtec ready and available for the beginnings of an algae bloom, but maybe I won't have to use it for awhile. The fish are all basically still tiny. Way too little to provide a fishing experience. Maybe we're close to two years away from having a good fishery.
249 bluegill that are 3-4 inches.
35 slightly bigger age-2 bluegill
125 yellow perch that are also quite small. Maybe 5-8 inches.
4 steelheads just for the fun of it. They'll probably last another week or so until we harvest them out.
The feedings are very enthusiastic at least. :-)
I used the Earthtec (buffered copper sulfate) on the sediment/nutrient pond yesterday and I'll check it tomorrow to see if there was an effect. The secchi readings were .4 meter yesterday.
